Diagnostic dilemma: Man’s sudden attack was caused by Sudoku
Patient: 25-year-old male living in Germany Symptoms: During a ski trip in November 2008, a man was knocked unconscious by an avalanche and was buried under snow for 15 minutes. While trapped, his body tissues became starved of oxygen, causing a condition called hypoxia. Berend Feddersen, a neurologist at the University of Munich in Germany […]
Largest crowdsourced search for alien information, data from collapsed Arecibo Observatory reveals 12 billion “signals of interest”
With the help of more than 2 million citizen scientists and the legendary Arecibo Observatory, one of the largest searches for alien information in history is nearing completion. Launched in 1999, the SETI@Home project enlisted the help of millions of volunteers around the world to identify anomalous radio signals in data from the Arecibo Observatory, […]
Giant iceberg A23a, once the world’s largest iceberg, finally dies after 40 years at sea, turning into a bright “blue mush”
New satellite images show that once the world’s largest iceberg, A23a, has turned into a beautiful mass of striped “blue mush”, signaling its imminent demise. This moribund ice mass, until recently three times the size of New York City, is one of the oldest ice masses on record and is currently celebrating its 40th anniversary. […]
Artemis 2 mission update: NASA prepares first manned Artemis mission to the moon, deployment imminent
NASA is making final preparations for the imminent launch of its Artemis 2 giant lunar rocket, with crewed flights around the moon scheduled to begin as early as February 6. The Artemis mission aims to return humans to the moon for the first time in more than 50 years. The program is also scheduled to […]
Parkfield, San Andreas searches for ‘crystal ball’ to predict earthquakes in advance
It’s currently impossible to predict earthquakes before they occur, but scientists are inching closer to doing so with new and innovative ways to monitor the movement of the Earth’s crust. In this excerpt from When Worlds Quake: The Quest to Understand the Interior of Earth and Beyond (Princeton University Press, 2026), author Hrvoje Tokarčić, Chair […]
Iceman mummy Ötzi carried high-risk strains of HPV, study finds
A new study has found that the 5,300-year-old iceman mummy Ötzi and a prehistoric man who lived in Siberia 45,000 years ago both carried cancer-causing strains of human papillomavirus (HPV). Scientists analyzed ancient genetic data previously collected from these people and found that both were likely infected with HPV16, a preprint paper posted on bioRxiv […]
Is it okay to eat too much protein?
The U.S. federal government has just released a new version of the food pyramid, recommending that Americans eat more protein than previously recommended. Previously, the recommended daily protein intake was approximately 0.8g per kg of body weight. This recommendation was aimed at meeting the nutritional needs of the average sedentary adult. New dietary guidelines now […]

DNA from ancient viral infections aids embryo development, mouse study finds
A new study shows that a swath of DNA left in the mouse genome by an ancient viral infection is crucial for early development in the womb. The viral DNA turns on genes that give cells in early mouse embryos the potential to become almost any type of cell in the body, according to a […]
Metal compound identified as potential new antibiotic thanks to robot performing ‘click chemistry’
Iridium metal complexes are an unconventional but promising new antibiotic, a new study has found. The compound is one of more than 600 produced in a study published in Nature Communications in December. The researchers used robots to synthesize compounds, combining building blocks of metal and organic molecules to generate a huge chemical library in […]
